In order to be efficient and productive at work the need to focus on what you are doing is obvious. Water is one of the most valuable and simple tools to help you. The human brain consists of 85% water. When you are not properly hydrated your brain feels the effects, with headaches, poor concentration and reduced short-term memory. Even your ability to perform arithmetic and the rapidity of your psychomotor skills can be reduced. This is due to the fact that dehydration causes the level of energy production in the brain to decrease.


Recent studies reported in the British Journal of Nutrition have shown that a person’s ability to concentrate progressively declines when the body is subject to a water deficiency of just 1-2%. Researchers reported that test subjects showed degradation in mental alertness, associative learning, visual perception, arithmetic efficiency, short-term memory and reasoning ability. These effects were most often accompanied by increased tiredness and headaches.
